ABSTRACT:
A modified thermostable DNA polymerase having 5% or less of the 3'-5' exonuclease activity of the enzyme before modification and a DNA polymerase composition for amplifying nucleic acid, which comprises the modified thermostable DNA polymerase having 0 to 5% of the 3'-5' exonuclease activity of the enzyme before modification and an unmodified thermostable DNA polymerase having 3'-5' exonuclease activity or a modified thermostable DNA polymerase having 100 to 6% of the 3'-5' exonuclease activity of a thermostable DNA polymerase before modification; a method for amplifying nucleic acid by use of said modified thermostable polymerase or said DNA polymerase composition; and a reagent therefor.
